WILHELM KRUEGER,

OF LAKE PARK, IOWA.

DITCHING-MACHINE.

To all whom it may concern:

Be it known that I, WILHELM KEUEGEE, a

citizen of the United States, residing at Lake Park, in the county ofDickinson and State of Iowa, have invented certain new and usefulImprovements in Ditching-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention,

' such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to new and useful improvements in ditchingmachines and it is an object of the invention to provide a novel deviceof this character wherein the earth loosened may be suitably elevatedand dumped to one side of theditch being formed.

It is also an obj ect of the invention to provide a novel device of thischaracter wherein the cutting plow may be adjusted vertically withrelation to the frame of the machine for varying the depth of cut.

It is also an obj ect of the invention to rovide a novel device of thischaracter w ich will be sim le in construction, eliicient in practice ancomparatively inexpensive to manufacture.

With the above and other objects in view,

the invention consists in the details of construction and in the novelarrangement and combination of parts to be hereinafter referred to.

In describing the invention in detail, reference will be had to theaccom anying drawings forming part of this speci cation, wherein likecharacters of reference denote corresponding parts in the several views,and in which,

Figure 1 is a central, longitudinal section of the machine, embodyingthe invention. Fig. 2 is a front elevation thereof, and, Fig. 3 is aperspective view of a detail of the invention.

In the drawings, 1 denotes a frame suitably su pported on a rear axle 2and a front axle 3. Said axles 2 and 3 have mounted thereon the wheels 4of any ordinary or preferred structure. Approximately centrally thelength thereof, the frame has secured to its opposed faces the brackets5, in which are mounted the wheels 6, said wheels being so supported asto permit the passage therebetween of the vertical standards 7. Thesestandards have secured at their lower edges the plow or cutting blades 8and are also united at their ends by the cross bar 49. The standards arefurther connected above the plow or beneath Specification of LettersPatent.

Y the frame by a cross piece 10. The cross piece 10 is provided at apoint centrally of the standard 7 with an eye 1 1, to which is secured aflexible member 12, which passes up over a pulley 13 and is secured to adrum 14. The pulley 13 is mounted between two upstand- Ing members 15secured to the frame and the drum 14 is mounted between two inclinedmembers 16 extending from the frame 1 to the members 15 adjacent theirupper ends. The drum 14 is rotated through the medium of a crank 17. Itis thought by this arrangement to be obvious how the position of theplow 8 with relation'to the frame -1 may be adjusted or varied.

Pivotally engaging the cross bar 9, is an apron 18 of a chute 19. Thischute has one end portion 2O arranged on an incline with the mainportion of the chute and this inoline portion is angular, as fully shownin Fig. 3. By this arrangement, it will be observed that the earthloosened by the plow 8 and forced u the chute 19 will be discharged bythe angular portion 2O to one side of the ditch, as is indicated inFig. 1. The chute 19 adjacent its lower end and at the junctiontherewith of the angular portion 20, has projecting upward from itssides the perforated ears 21, in which are mounted rollers 22. Overthese rollers pass an endless apron belt 23 having projecting therefromthe blades 24. The apron 23 is moved in such a direction as to cause theblades 24, when adjacent the chute 19, to move upwardly and therebyelevate the earth loosened by the plow 8.

The upper end of the chute 19 may be supported as desired, but it ispreferable that it rest loosely on a roller 25 mounted on the frame 1 ofthe machine. By this arrangement, freedom of movement is assured thechute 19 when the plow 8 is being elevated or lowered.

In order that the apron 23 ma be operated, the shaft 26 of the upper roler 22 projects beyond one side of the chute 19 and to this projectedportion is fixed a beveled gear 27, which meshes with a gear 2S fixed tothe shaft 29 which is telescopic with relation to the shaft 30. Theshaft 30 has fixed thereon a bevel gear 31, which meshes with a gear 32,carried by a sleeve 33 embracing the axle i' 2 and secured to the wheel4.

The shaft section 30 is mounted in a bearing 34 pivotally mounted on theaxle 2, or, in other words, is so mounted as to rotate therearound tocompensate for the different posient instance, said frame is shown asconnect-l ed with a suitable kdrafting mechanism 38.

The standards 7 also pass between the rollers 39 arranged in verticalalinement with the rollers 6, hereinbefore referred to. These f rollers39 are suitably mounted in brackets 40, of an approximate invertedV-shape, having their free ends secured to the frame. By thisarrangement any undue lateral movement of the standards is obviated.

I claim:

1. In a ditching machine, the combination of a frame, a plow, means foradjusting the plow vertical with relation to the frame, a chute leadingfrom the plow to one side of the frame said chute being pivoted to theplow yand loosely engaging the frame and an elevating means acting inconjunction with the chute.

2. In a ditching machine, the combination with a frame; of rodsvertically movable with relation to the frame, a plow carried by therods, a chute pivotally secured at one end between the rods, a rollermounted on the frame, said chute resting on said roller and an elevatingmeans acting in conjunction with the chute.

3. In a ditching machine, the combination of a frame, rollers mounted inthe frame, brackets carried by the frame, rollers mounted in thebrackets, above the rollers of the frame, rods passing between theroller of the brackets and the roller of the frame, a plow carried bythe rods, a chute leading from the plow and a conveying means acting inconjunction with the chute.

4. In a ditching machine, the combination of a frame of rods verticallymovable with relation to the frame, a pulley mounted above the framebeneath the rods, a cross bar connecting the rods, a plow carried by theframe and a flexible connection secured to the cross bar passing overthe pulley and engaging the drum, a plow carried by the lower ends ofthe rods and a chute pivoted to the plow and loosely engaging the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILHELM KRUEGER.
